redis三主三从部署

Posted 2021-01-17

服务器A：192.168.3.188 centos7
服务器B：192.168.3.189 centos7
关闭firewalld防火墙，关闭selinux；
redis 版本4.0.1，至少6台做redis cluster

yum -y install wget vim tcl gcc make
mkdir –p /usr/local/redis
cd !$
wget http://download.redis.io/releases/redis-4.0.1.tar.gz
tar –xvf redis-4.0.1.tar.gz
make
make test-没报错继续
报错了修改这里
/usr/local/redis/redis-4.0.1/tests/integration
replication-2.tcl里面的after 10000
拷贝redis命令到环境变量
cp -a src/redis-server src/redis-cli src/redis-sentinel src/redis-trib.rb src/redis-check-aof src/redis-check-rdb src/redis-benchmark /usr/local/bin/
mkdir cluster-redis
cd cluster-redis
mkdir {7000,7001,7002}

其中一个redis.conf配置文件内容

其它redis配置文件修改相应的端口和数据库名称就好了
依次启动redis

redis-server /usr/local/redis/cluster-redis/7000/redis.conf
redis-server /usr/local/redis/cluster-redis/7001/redis.conf
redis-server /usr/local/redis/cluster-redis/7002/redis.conf——另一台服务器也启动三个redis节点

提前安装以下两个依赖，zlib和openssl

yum -y install zlib-devel
yum install openssl-devel -y
再安装ruby，ruby-2.3.4.tar.gz，解压后编译安装
./configure
Make && make install
Ruby –v 版本在2.2.2以上

安装redis，如果无法安装，切换gem源，看以下链接更换gem源
https://ruby.taobao.org/

Gem install redis

启动集群

redis-trib.rb create --replicas 1 192.168.3.188:7000 192.168.3.188:7001 192.168.3.188:7002 192.168.3.189:7000 192.168.3.189:7001 192.168.3.189:7002

登陆某台节点

redis-cli 192.168.3.188 -c -p 7001
